SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer.
Use the following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position
and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.)
to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the
unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE
LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE
ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper
wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure
the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic
cabinet part on the unit. When testing 3 wire products, the resistance measured to the product
enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed
input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and
infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard,
and the unit must be repaired and rechecked before it is returned to the customer.

Product Description
The Bose® Panaray® System Digital Controller II is the next generation of the Bose Panaray
Digital Controller. It is a 1U rack mount controller with 2 inputs and 4 outputs, and it’s primary
purpose is to provide selectable loudspeaker EQ. It utilizes a TI TMS320D707RPF digital signal
processor to provide Bose speaker equalizer curves for all current and future speaker products.
The unit’s firmware is field upgradeable via a serial port and will not support dual mono preset
operation.
The controller is a world-wide product that utilizes a switch-mode power supply, allowing it to
operate on any line voltage from 100V to 240VAC, 50/60Hz. The Controller II is also RoHS and
WEEE compliant.
The Panaray System Digital Controller II replaces the Panaray System Digital Controller.
The controller utilizes a digital signal processing (DSP) architecture to provide Bose speaker
equalizer curves for all current and future loudspeakers.
The DSP engine has the capability to run the following operations simultaneously:
- Parametric EQ: One stereo (or mono) seven band parametric equalizer capable of the
following
• Seven band parametric
• Six band parametric with high pass
• Six band parametric with low pass
• Five band parametric with a high pass and low pass
- Crossover: Two mono or a single stereo crossover
• Choice of Butterworth, Linkwitz Riley, and Bessel Filters
• These support 1st, 2nd, 3rd and 4th order slopes.
• Output Limiter: Four mono or two stereo output limiters capable of being assigned
to any of the four outputs.
- Routing: Independent routing of input program material to any of the four outputs.
- Line Delay: Delay is available only to presets located in the Bass Array bank
• None of these settings are user programmable.
• The controller has the ability to accommodate up to 180 ROM presets capable of
supporting all combinations of Bose speakers products. The speaker presets are
not editable by the end user.

Theory of Operation
The Panaray® System Digital Controller II is a 1RU chassis with two XLR audio inputs, and four
XLR audio outputs. It incorporates an LCD display on the front panel for setup. Setup and
menu navigation are accessed by using four directional push buttons, and a Select/Load button.
Signal present (green) and Clip (red) indicators are visible on the front panel. The PSDC-II
incorporates a universal switch-mode power supply and an IEC AC receptacle is on the rear
panel. The rear panel includes an RS232 serial connection to facilitate software upgrades.
The following is a brief functional description of the PSDC-II PCB assemblies.
•Includes Standby mode that is controlled by the front panel Standby switch
Rear Panel PCB:
•Two analog XLR audio inputs
•Four analog XLR audio outputs
•RS232 serial port (DB9 connector)
•Output relays for On/Off pop control
Front Panel PCBs:
•LCD display module
•Navigation buttons
•Signal Present/Clip indicators
•Standby button
DSP PCB:
•DSP for audio processing with associated memory
•A/D and D/A conversion
•CPLD for miscellaneous logic, mute, LED drive, and transceiver functions
•Local voltage regulation for DSP Core
•Selectable analog gain circuitry
Switch-Mode Power Supply
Refer to the schematic sheet for the Switch Mode Power Supply PCB, part number 298155, for
the following information. The information inside the brackets [ ] are the component’s grid
coordinates on the schematic sheet.
The power supply is a primary switch mode power supply (SMPS) that generates DC voltages
for the other PCB’s. It can be put into a standby mode using the on/off header XS2 [C6] on the
SMPS.
55
Page 56
Theory of Operation
Switch-Mode Power Supply (continued)
Digital circuits run on 5VDC and 3.3VDC to minimize power consumption. The DSP core
voltage is 1.2V, and uses a separate regulator (U504) on the DSP PCB. All analog audio circuits are powered at +/- 12VDC to maintain a large dynamic range. Total power consumption is
less than 15W. The power supply is non-repairable.
Input/Output PCB
Refer to the schematic sheet for the Input/Output PCB, part number 298152, for the following
information. The information inside the brackets [ ] are the component’s grid coordinates on the
schematic sheet.
The Input/Output PCB contains the input and output XLR connections, signal conditioning
circuits, On/Off pop control circuits, and the RS232 transceiver. The two balanced inputs from
J601 and J602 [D2 and D4] are passed to the DSP PCB for Gain Control and A/D conversion.
The four output signals, DAC CH1 to CH4, come from the DSP PCB, and the differential drive
buffers connect to the output XLR connectors J701 [A5], J702 [B5], J703 [A11] and J704 [B11]
through output relays K1 [A4], K2 [A10], K3 [B4] and K4 [B10] that are controlled by anti-pop
circuits at turn-on and turn-off.
The DB9 connector P301 [D11] located on the rear panel, labeled COM, is also mounted on the
input/output PCB. This connector is used to update the firmware/DSP code in the PSDC II.
Refer to the software update procedure located in this manual for instructions.
Button and LED, Standby Switch and LCD Display PCBs
Refer to the schematic sheet for the Button and LED PCB and the Standby Switch PCB, part
number 298160, for the following information. The information inside the brackets [ ] are the
component’s grid coordinates on the schematic sheet.
The front panel has three separate PCBs attached; the Button and LED PCB, the On/Off Switch
PCB and the LCD Display PCB.
The first is the Button and LED PCB, which contains the five push buttons for menu navigation,
and the signal present/Clip LEDs. The navigation and Select/load button are scanned by the
DSP (U501) [DSP schematic sheet, location A/B 5/6]. The signal present and clip LEDs are
driven by the DSP through U507 [DSP schematic sheet, B3].
The second PCB located on the front panel is the LCD Display PCB. This is a separate PCB
because it incorporates chip-on-board technology that is non-repairable. This PCB assembly is
bought as a module from a third-party vendor. If the display fails, the entire PCB assembly must
be replaced. The display is a blue backlit LCD module that is controlled through the CPLD IC
U502 [DSP schematic sheet, A10]. The Display PCB is fed from J303 [Button and LED PCB
schematic sheet, C/D1] located on the Button and LED PCB. The control and display signals for
the Display PCB are fed to the Button and LED PCB at J302 [Button and LED PCB schematic
sheet, A/B1] from the DSP PCB at CN500 [DSP schematic sheet, B2].
56
Page 57
Theory of Operation
Button and LED, Standby Switch and LCD Display PCBs (continued)
The third PCB assembly located on the front panel is the standby switch PCB. This is a 2PST
switch (SW106, [D4]) that controls the remote On/Off feature on the SMPS and is used to put
the unit into Standby mode when not in use. The remote On/Off feature on the SMPS is also
used by the anti-pop circuit on the Input/Output PCB. J105 [C2] connects to the I/O board,
carrying the relay power enable/disable signal to control relays K1 – K4.
Digital Signal Processor PCB
Refer to the schematic sheet for the Digital Signal Processor PCB, part number 298154, for the
following information. The information inside the brackets [ ] are the component’s grid coordinates on the schematic sheet.
The DSP PCB contains the signal processing subsystem, the heart of which is the TI
TMS320D707 microprocessor IC U501 [A/B 5/6]. The two differential audio inputs from J601
and J602 come from the Input/Output PCB, and travel through a software selectable differential
gain circuit using the OPA1632 U516 [C/D3] and ADG452 U514 [C/D5]. From there, they enter
U512 [C10] (the PCM1804 high performance differential A/D converter). Signal processing is
done at 44.1 kHz, 24 Bit within the DSP subsystem. Once processed, the four output signals
are sent to U508 [B9] and U509 [C9] (the differential D/A converters) and then over to the Input/
Output PCB via CN502 [C11]. J501 [A8] accepts a JTAG header for interrogating the DSP chip.
J500 [A9] is used to program the CPLD (U502, [A10]) on the production line. The system uses
a 4Mbit flash memory (U500 [A2]). All code (except the CPLD) is up-loadable over the serial
port to facilitate field upgrades.
The main system oscillator is 22.5792MHZ Y500, [B9]. It is conditioned by the CPLD, and
presented to the DSP which in-turn generates the necessary clocks for the system (A/D, D/A,
LCD).
